Hou Yu's case, there has been a new change in the case, Hou Yu's secretary Zheng Yan died, it seems that she jumped off the building, but in fact she was murdered.

Now, Ding Shutong has completely agreed with Wu Gan's statement, but at this point, there are still many doubts.

Ding Shutong asked directly: "Mr. Wu Qian, I completely agree with your speculation, this is indeed a murder case, but some details, now ...... If nothing else, the question of this dummy alone, I am now sure, is that he was bent, but why did the murderer do this? Or, how did he bend this dummy? In my opinion, the reason why he did this, or simply bent this dummy, should be a prop for delayed killing. Then, I can also make a bold guess, that is, the murderer must make his own alibi to make this kind of delayed killing props, and I think this judgment is fine, but how did he do it? What kind of delay prop is it?"

Yes, a key point has emerged, how to do it.

Zheng Yan's death is almost certainly a murder, but there are many doubts about the details of her death.

Wu Qian showed the rebound of the dummy, and the position of the dummy is completely wrong, these are all good, but if the dummy is bent, you know, he can bounce back immediately, will there be someone who has been pulling this dummy?

Obviously, it can't be, because when Hu Jinhui and everyone came in, there was no one here.

Their own employees, as well as Qiao Sheng, Hu Jinhui and others, are also very curious about this.

And Wu Qian smiled, "Do you remember the sound that Mr. Hu said before?"

Sound?

Hu Jinhui said: "It's a bang. ”

Wu Qian nodded, "Yes, that's it." ”

Qiao Sheng was really puzzled, "What's wrong with that voice?"

Wu Qian didn't speak, but came to the side of the butterfly machine.

The lounge, which is also a small fitness room, has a butterfly machine and a fitness rack, both of which are not very large, but more useful.

The butterfly machine is a thing that exercises the chest muscles, and the simple description is that the two arms hold the two wrenches, saying that they are two wrenches, but in fact, they are more like two thick cushions, and then, the exercise is, the two arms exert force in the middle.

In this way, it is an exercise, and the pectoral muscles are contracted and forced.

The reason is very simple, however, this machine is still a little complicated, because there must be a counterweight on one side, this counterweight, if there is some deviation, such as only on the right or left side, this will make the force a little uneven.

Of course, if it is a good butterfly machine, there should be no such problem, the whole action is like a butterfly, and the chest muscles are getting bigger and bigger.

This butterfly machine is also right between the window and the door, that is, between the dummy and the door.

And Wu Gan, at this time, directly pushed with one hand, a wrench was pushed by him, and the interesting thing is that the other wrench also moved, in short, moving one, the other one was also moving, and the two wrenches would finally converge together.

Suddenly, Wu Qianyi let go.

Bang!

As soon as you hear this, everyone understands!

"This is it!" Hu Jinhui said, pointing.

"That's right, that's right. Qiao Sheng also understood.

"The voice should be gone. The same is true for Mu Feng and the others.

Ding Shutong looked at Wu Gan, he admired it very much at this time, and asked: "Mr. Wu Gan, what you mean should be that this thing and the dummy can be combined, and they can constitute a time-lapse prop for killing, right?"

Wu Qian nodded, "Wait a minute, I'll finish this prop." ”

Finish?

Can he actually get this prop for delaying killing?

"Everyone gathered in the middle. ”

Wu Gan commanded, and then he picked up the two rubber belts from the ground.

This thing is relatively thick, about more than an inch thick, quite thick, in fact, those who have practiced yoga know that this thing is very common, in addition, some fitness actions will also be used, for example, on the two legs, so that you can exercise the muscles of the legs.

It's very simple, and the price is not expensive, but what is Wu Gan picking up this thing for?

I saw that Wu Gan pushed the butterfly machine up again, and the two wrenches were closed together again, as if a butterfly had caught its wings.

At this time, Wu Gan used a rubber belt to put on the left wrench of the butterfly machine, that is, the wrench close to the dummy, but the place where he put it was more special, that is, the lower part of the wrench.

You know, this wrench is like a board, quite thick and wide, so it's a bit difficult to put it on.

But fortunately, it was stuck, and then, Wu Gan did not relax at all, pulled the rubber belt, and walked towards the door.

This lounge, because there is fitness equipment, the door is actually quite thick, and the handle on the door is relatively hard.

The handle is in the shape of a normal L, but at this time, because the door is closed, the handle is horizontal, parallel to the floor.

With such a handle, about 2 meters away from the butterfly machine, Wu Qiang worked very hard, so he put the other end of the rubber belt on the doorknob.

It's done!

The handle is parallel, and the other end of the rubber belt is attached to the lower part of the wrench of the butterfly machine, which naturally produces a twisted appearance.

Like a flattened letter X.

And then, Wu Qian used another rubber belt, which was easily put on, or the left wrench of the butterfly machine, which is close to the dummy.

However, this time it was the upper part of the wrench that was put on.

After that, Wu Gan still pulled the rubber belt, he pulled the dummy hard in the direction of the door, that is, the butterfly machine, and then put the rubber band on the dummy's neck.

So......

"It's done. Wu Qian said with a smile.

I saw that a prop connected to the doorknob, a butterfly machine, and a dummy was made.

"This, this ......"

"Can this be done?"

"Is this really okay?"

Everyone didn't believe it, but Wu Qian was very simple.

"Don't worry, wait a minute. Wu Qian walked out from the place where the pantry was connected.

Then, not long after, the doorknob was turned.

Because the doorknob is parallel, and when the door is opened, it has to rotate downward, so the doorknob becomes at right angles to the ground, and at this time, it ......

Bang bang!

Because of the change of the doorknob, and the rubber belt can't hold up, it slides directly from the bottom of the doorknob, and the other end of it is in the lower part of the butterfly wrench, this power, coupled with the smoothness of the doorknob, the metal is very bright, which makes the rubber belt slip off.

And then, the two wrenches of the butterfly machine opened in an instant from the merged state, and the counterweight fell fiercely, and the other rubber belt naturally bounced back with the wrench on the left, and the dummy changed from bending to rebounding!

"I understand! I understand it completely!" Ding Shutong suddenly realized.

That's right, that's it, it's just ...... The rubber band, tied around the dummy's neck, flew straight out of the window.

Obviously, this is how Zheng Yan was pushed off the tall building!
